A Master of the Dark Jedi arts, who was a male Human, was in service to Darth Malak, the Dark Lord of the Sith, within his Sith Empire during the time of the Jedi Civil War. In the final battle of that conflict, this Dark Jedi was positioned on the Star Forge, the ancient Rakatan space station that was under Malak's command and powered the Empire's military campaigns. Throughout the battle, he kept watch over Revan, the Jedi who was once a Dark Lord but had been redeemed, while Revan was aboard the Star Forge, and he relayed information about Revan's advancement to Malak.
This Dark Jedi Master made an appearance in the video game Star Wars: Knights of the Old Republic, which was released in 2003.
